COIN-CONTROLLED STRENGTH-TESTER.

SPECIFICATION forming part of Letters Patent No. 415,949, dated November 26, 1889.

Application filed April 1, 1889. Serial No, 305,601. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAV SOEDING, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Coin-Controlled Strength-Testers; and I do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawings.

This invention has relation to coin-controlled stren gth-testers of the character shown and described in Letters Patent of the United States No. 399,942, granted to me on March 19, 1889, and has forits object to simplify the construction and increase the efficiency of certain features of the invention shown in said Letters Patent.

My invention has relation to certain details of construction; and it consists in the combinations of parts, as hereinafter fully described and claimed.

In my invention first above mentioned I employ a grooved wheel with a pinion thereon meshing with a rack on the pulling-bar and secured on a shaft journaled on the easing. A cord passes around this wheel and receives motion therefrom, so that if the handles be allowed to fly back to normal po sitions after operation the cord with its pointer and the grooved wheel will. travel coincidently with the shaft and at very great speed, which has resulted in the slipping of the cord if the same stretches and becomes loose and in the breaking thereof and the general racking of the entire registering mechanism.

Myimprovement dispenses with the rack and pinion and journals the grooved wheel on the shaft and the latter in the casing, said wheel having a rigid pawl engaging with a tooth on a collar secured on the shaft, so that when said shaft is rotated through the me dium of a cord passing around a grooved wheel formed on one of the gears with which the oppositely-moving handles connect, and secured at each end to the shaft, the large grooved wheel will travel in one direction as fast as its shaft. hen, however, said shaft rotates in the opposite direction in response to the flyingback of the handles, the grooved wheel will rotate much more slowly and easily back to its normal position, because of the same being actuated by a helical spring of slight tension encircling the shaft and secured to a collar thereon. The cord passing around said wheel is secured thereto at opposite ends, so that there can be no slipping thereof. Thus the objections of this feature of my previous invention are effectively obviated.

Another improvement is the substitution for the straight coin-lever shown in the aforesaid Letters Patent of a lever bent beyond its pivotal point in order that its outer end will drop below the plane of the springon the pulling-bar without striking thereon,thusobviating the necessity for providing means for jarring the coin off said lever, the latter when weighted with a coin being supported by an arm on one of the pushing-bars, so that the handles must be operated slightly before the lever will tilt and the coin slide off.

My improvements will be clearly understood by reference to the accompanying drawings, wherein- Figure 1 is a rear View of a strength-tester with my improvements applied thereto, the casing thereof being in section. Fig. 2 is a side elevation of the same with the casing in vertical longitudinal section and partly broken away, and Fig. 3 is a plan view of the coin-lever detached.

A represents the main grooved wheel,having the elongated hub-a, encircling loosely the shaft B, and having secured to the face of one of its spokes and on a side opposite to that of its hub a rigid pawl a, engaging normally with a tooth b, on the rim of a collar b, secured to said shaft and resting against the face of said wheel. Secured to the shaft B, andlightly contacting with the edge of the hub to, is another collar 19 which, in conjunction with the collar 1), prevents lateral displacement of the wheel A, but doesnot retard its rotation on its shaft. Shaft B is provided at each end with pivotal hearings on the conical ends of screws 0 c, which are threaded into openings in the casing and are provided with jam-nuts C O to prev'ent their becoming unscrewed and the shaft being dislodged. The advantage of this form of bearing over the journaling of the shaft in the casing is quite obvious, as the friction therein is reduced to a minimum. Shaft B has se-' cured to it near one of its ends and on the side of the wheel A nearest the collar Z) another collar b similar to H and having a small opening in its face for the reception of one of the ends of a small helical spring D of low tension, the other end of which is secured to the hub a of the wheel A by means of a screw d in said hub. Secured to the shaft B near its other end is an elongated collar 0, of slightly larger diameter than said shaft and having diametrical holes d (Z therein corresponding with similar holes in the shaft on each side of this collar 6, andin the shaft B are screws 6 e Secured to the screw (2 is a piece of catgut F or other nonelastic material. This piece or belt F is then passed through the hole (Z and then around the smaller grooved wheel formed on the gear-wheel G.' Said belt is then wound once around the collar 6 and then passed through the opening (Z in a direction opposite to that of its other end, after which it is secured to the screw 6, so that when the gear Gand its corresponding gear G (which latter gear G serves merely as an idler to equalize the draft on both arms of the handles H I) are actuated by said handles through the medium of the rack bars or extensions 72 7t it" the shaft B will be rotated correspondingly therewith by the wheel 9 through the belt F, and the motion communicated to the wheel A through the medium of the pawl a and the tooth b on the collar b. The return movement of the handles will be communicated to the shaft B by reason of the reverse winding of the belt F on the collar e. This movement is not, however, transmitted to the wheel A, for the reason that the latter is loosely journaled on the shaft, so that the provision of the spring D is necessary to -bring said wheel back to its normal position and the pawl thereon into contact with the tooth Z), which spring D is of only sufficient tension to cause the wheel to easily return to its original position and the pointer on the cord Nto its lowest point in the indicatortube, and thus avoid the breaking of said cord and the disarrangement of any of the parts of the registering mechanism.

As will be observed in, the drawings, the pointer above referred to and the other parts of the registering mechanism are not shown; but only so much of the indicatontube and cord are shown as is deemed necessary for the illustration of my invention, for the reason that said registering mechanism is of the same character as that shown and described in my aforementioned Letters Patent.

In order to prevent breakage of the tooth l) by a too violent or sudden contact of the pawl a on the wheel A therewitlnwhich limits the rotation of the latter, there is provided a rubber-coated pin a on one of the spokes of the wheel A, which contacts "with a curved upright L in the bottom of the casing M.

other obstruction out of the receiver.

To prevent slipping of the cord N on the wheel A when the latter is rapidly rotated, said wheel is provided with an opening a in the groove (0, which permits of the passage of the ends of a cord N, after which said ends, when the pointer has been properly adjusted in the tube 0, are fastened to the spokes of the wheel on opposite sides of the opening a",- as shown at a n so that when the wheel is rotated in either direction the cord which passes over the guide-wheel or idler N will be operated correspondingly.

As shown in the drawings, the rack-bars 7L h i i, which are terminations of the curved arms 1) i on the yoke P and the handle I, which move in opposite directions in a horizontal plane, as in my said patent, are guided in the standards K, secured byscrews k to the casing M, which standards K are cut out or have a portion removed, as shown at M, for the passage of the rack-bars h h i i" and the gears G G, which latter are journaled on the ends of the screw-bolts g g in the sides of the casing M, having jam-nuts g thereon for maintaining said holesin their proper positions, and thus keep the gears in alignment with the racks.

The pulling-handle H is, provided with the usual square bar or rod 71?, encircled by a helical spring P, and having on its end the yoke P, with the shoulder 71. for engagement with the end 0* of the locking-bar R, which locking-bar is connected to the coin-lever S by means of the link or connection 0*, pivoted on pins 7' This coin-lever is pivoted on the pin t in the hanger T, secured in the top of the casing, and just beyond its pivotal point has an offset or bend s,which is rounded underneath, as shown at 5 so that in the event of a coin becoming stuck in the receiver and failing to slide therefrom or from any other cause the arm V, which is secured in the arm i? of the handle I, will, upon the return of said handle to its normal position, ride upon the rounded under side s -of the bend in the coin-lever S, raising said lever with sufficient velocity to throw the .coin or The arm V also prevents the coin from dropping or sliding from the coin-lever prematurely or before the handles have been operated bythe rounded end o thereof resting a sufficient distance from and under the lever S to allow the outer or coin-receiving end of said lever to drop only a distance sufficient when a coin is placed thereon to slightly elevate its inner end, which motion is communicated to the locking-lever B through the medium of the link 0*, thus causing the disengagement of the end of said locking-lever with the shoulder h of the yoke P. A further operation of the handles is necessary to bring the end of the arm V from beneath the offset of the coin-lever, in order that the latter may drop a sufficient distance to cause the coin to freely slide therefrom.

As will be observed, the coin-lever S is bent sufficiently to cause the outer end 3', which is in a horizontal plane with the rear end 8* of the same, to clear the spring on the pulling-handle, thus allowing the said coin-lever to drop or tilt sufficiently to cause the coin to slide off without any assistance whatever. The coin tube or conveyer U is also bent or curved, so that the outlet end of the same will be in line with the coin ring or receiver 8 and has the lip "a, for assisting in the converting of the coin from its vertical to a horizontal position. Only a slight operation of the handles is necessary to allow the coin-lever to drop to its fullest extent.

Having thus described my improvements, I do not wish to be understood as claiming, broadly, any of the features of my aforesaid Letters Patent; but
